Easy Deep Sky Astrophotography - Stacking Your Images With Deep Sky Stacker
About | Information | History | Online | Facts | Discovery
This video is the second part of a 3 part series that shows you how to take pictures of deep space objects using only a DSLR camera on a static tripod. In this video the pictures of Messier 3 are uploaded along with the calibration frames into the free to download Deep Sky Stacker. This software aligns all the images and reduces the noise to create a final more detailed and better quality image for later processing. The video shows you the steps involved in stacking. For Part 1 of the guide please visit http://www.learnastronomyhq.com/articles/easy-deep-sky-astrophotogra.html which will show you how to take the pictures to use for stacking.

I converted all my JPGE files from my canon 450d to TIFF files. And dss isnt callibrating my images. so a star looks like a line/comet

What the hell is that sound coming from you. Sounds like you have excessive saliva. Annoying move the mic away.
-
Too many steps for me. I'd rather pay for a product to keep it simple.
-
stop the smacking pls,it is very annoying
-
what was the name of the stacking software.? thanks
-
hmm. It seems to play okay now. Thanks for letting me know
-
I found this today. It's sounds great and informative but the video keeps stopping after ten seconds. I've tried it many times now throughout the day... (boo hoo)

Thanks Paa. DSS will stack as low as 8 stars. For this technique of lots of short exposure high noise images I found if you use too few stars you get a very small percentage of images stacked and then can't pull the image out from the noise. Thank you for the comment

You can stack as low as 12-15 star detection. However it is best to try and have a detection of 50 or more. 200 isn't necessary to get it to stack images. Just to correct you there.

Unfortunately not. The stacking process improves the signal to noise ratio. You need lots of slightly different images of the object. The object is so dim and the exposure time so short that each image will contain a few photons of the object. Stack them up and the signal improves and the random background noise (which is a bit different in each frame) is suppressed.

If i take on single picture then copy it 400 times and stack them ,can i get the same result if id take 400 individual pictuers and stack them?

What that man said. Thank you David, you beat me to it
